TRAVELING LUBRICATOR FOR GUIDE-BARS.

Specification of Letters Patent.

Patented Dec. 3,1912.

Application filed May 20, 1910. Serial No. 582,354.

To all whom 'it may concern:

Be it known that T, JOSEPH H. HIRZ, a citizen of the United States, residing at Milwaukee, county of Milwaukee, and State of Wisconsin, rave invented new and useful improvements in Traveling Lubricators for Guide-Bars, of which the following is a specification.

My invention relates to improvements in lubricators for elevator guides.

The object of my invention is to provide a form of construction which will be durable, economical in the use of lubricant and comparatively inexpensive.

In the following description, reference is had to the accompanying drawings, in which- Figure 1 is a side elevation, showing my invention in its relation to the elevator car and guide. Fig. 2 is a plan view of a de vice embodying my invention and an elevator guide to which it is applied. Fig. 3 is a sectional view of the lubricator drawn sub stantially on line .v.r of Fig. 2. Fig. 4 is a transverse sectional view drawn through the spring actuated wick holders immediately above their supporting members. Fig. 5 is a. sectional view, drawn on line y y of Fig. 4. Fig. 6 is a sectional view, drawn to the same plane as in Fig. 3, but showing a modified form of construction. Fig. 7 is a detail perspective view of the modified structure shown in Fig. 6, showing a portion of the cover of the oil receptacle, wick holder, pad, and wick. Fig. 8 is a detail view of the same, showing the under surface of the oil receptacle cover with the wick holders, pads and wicks, the side walls of the receptacle and the elevator guide being illustrated in cross section.

Like parts are identified by the same reference characters throughout the several views.

The receptacle A for the lubricant may be supported from the elevator car by any convenient means, such for example, as the rod A and clamping member a. The receptacle is provided with a recess in one side, into which the elevator guide B is adapted to project. The walls C of this recess at the respective sides and along the outer margin of the guide 13, extend upwardly from the bottom of the receptacle to a point preferably somewhat above the middle portion of the receptacle in order to retain a body of lubricant D in liquid form within the re ceptacle. Above the upper margins of the walls C, a setof pads E are supported by pad holders F in a position to bear against the sides and outer margin of the guide B. The pad holders F each comprise a frame, (preferably rectangular), crossed at the rear by a plate F, over which a wick G is hung. That portion of the wick G which passes within the frame between the plate F and the pad E, is adapted to transfer lubricant from the wick to the pad E, the lubricant being raised by the wick from the body of liquid below the pad, partly by capillary attraction and partly owing to the splashing of the lubricant when the elevator is in motion.

The pad holder frame is resiliently supported from the casing. This may be accomplished by providing the frame or the plate F with a supporting rod H seated in a suitable socket H formed in a depending portion of the cover. The frame is pushed outwardly from the socketed member H to cause the pad E to bear with a light pressure against the guide B, said pressure being applied in the direction shown in Figs. 1 to 5 inclusive, by means of a spring I coiled about the rod H and interposed between the socketed member H and the plate F. The rod H is preferably arranged to project through a hole in the wick G, but it is not material whether saidrod extends through the wick since any means of connection between the rod and plate F may be adopted, as desired. The pads E may be preferably supported between the margins of the holder frame F, and it is not essential to connect the pads to the holder frame by any other means, since the guide B prevents the pads from falling out of their positions.

Referring to Figs. 6, 7 and 8, it will be observed that I have provided pad holding frames J, which are supported by outwardly extending lips J engaging in suitable grooves formed by guides K attached to or integrally formed with the cover L of the lubricant receptacle. With this construction, the wick G may be merely looped over a rod K connecting the side margins of said frame J and a flat spring M, having one end secured to the cover L and the other end looped partially over the rod K, may be employed to impart the desired pressure of the pads E upon the elevator guide. The spring M may be arranged with a portion M thereof bearing directly upon the wick G. With this construction, both portions of the wick, which hang from the rod K, are interposed between the part M of the spring and the lubricant distributing pads E.

I am aware that oil distributing pads have been heretofore employed in connection with lubricating devices for elevators, in which the lubricant is supplied to the pads from a point above thepads by means of a duct through which the lubricant flows by gravity. I am also aware of the fact that it has been attempted to use such pads in a device depending upon the splashing of the lubricant in an oil cup below the pads to supply oil to such pads, but I believe that I am the first to conceive a construction in which a wick is employed in combination with oil distributing pads, whereby said wicks convey the oil by capillary attraction to the pads. I thus avoid an excessive feed of oil, such as results where gravity is relied upon to supply the pads and I also avoid being dependent upon the splashing of the oil. I therefore consider this feature of great importance, since the splashing of oil is uncertain and is due to a more or less defective construction in the elevators and their guides, and the more perfect elevators are therefore less adequately lubricated by such devices than those which are less perfectly constructed. By my improved construction, however, a sufficient and constant supply of lubricant may be supplied without waste.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a device of the described class, the combination with a receptacle for liquid lubricant, a pad holder and a pad supported thereby in position for contacting with an elevator guide, of a wick connected with the pad holder and supported with its lower end submerged in the lubricant and with one portion thereof in contact with the pad; said pad being removable independently of the wick.

2. A traveling lubricator device for guide bars consisting in the combination with a lubricant receptacle, a pad adapted to contact with and slide along the guide bar, and a pad holder, of a wick supported in contact with the pad and having its lower end extending into the lubricant containing portion of the receptacle; said wick being separated from the guide bar by the pad.

3. A traveling lubricator device for guide bars consisting in the combination with a lubricant receptacle, a stationary pad adapted to contact with the guide bar, and a pad holder, of a wick supported in contact with the opposite side of the pad from that in contact with the guide bar and having its lower end extending into the lubricant containing portion of the receptacle, together with means for pressing said pad against. the guide bar.

4. A traveling lubricator device for guide bars, consisting in the combination with a lubricant receptacle formed to embrace the guide bar on a plurality of its sides, of aremovable cover, a set of pads resiliently supported from said cover in position for contact with the respective sides of the guide bar, and wicks extending from the bottom portion of the receptacle into contact with the respective pads.

In testimony whereof I atiix my signature in the presence of two witnesses.
